What is the simplified form of (-3^3y^2)(5xy^-1)?

To solve this problem you must apply the proccedure shown below:
 1- You have the following expression given in the problem above: (-3^3y^2)(5xy^-1). The negative exponent of y^-1 indicates that y must be in the denominator with positive exponent 1. Therefore, you have:
 (-27y^2)(5x)/y
 -135xy^2/y
 2- By applying the exponents properties, you obtain:
 -135xy
 Therefore, the answer is: -135xy
